"We have had a difficult couple of years but since 2017 we introduced one of the most ambitious business transformation programmes ever implemented by a State company," said Aidan Murphy, Chair of the Bus Éireann Board.
"Since accepting the Labour Court recommendation in June 2017, and with the support of our staff, we have rebuilt our finances and refocused our efforts and resources on delivering excellent standards for our customers who rely on the thousands of services we provide every day throughout the country."
Anne Graham, Chief Executive Officer at the National Transport Authority said the investment "will enable the company to continue to increase its passenger numbers and to provide a viable alternative to car usage for people all over Ireland."
